The passing of properties from parental to offspring
AB
Heredity
The branch of biology that focuses on HeredityGenetics
A cross that involves one pair of contrasting traitsMonohybrid
Organisms that room homozygous for a certain trait and always produce offspring that have the same trait. For example: a purple flowering tree that always produces offspring through purple flowers.

You are watching: If purple flower color is dominant
